: Handrail (HANDRA) Hierarchy
Handrail (HANDRA) Hierarchy
The Handrail element (HANDRA) is a top level administrative element owned primarily by the STRU element as well as other administrative elements.
The Handrail introduces functionality enabling the user to create rule based arrangements and layouts of Handrails and introduces a new middle tier hierarchy to enable the decomposition of the Handrail into its individual components, TMPLs are used to represent the detail of the 3D model.
The underlying technology responsible for defining the route of the Handrail element is the Routing Path element, this provides the functionality to define an open path or closed boundary via the following;
•
Free form interactive sketching using the Route sketching functionality
•
Tracing existing profiles or boundaries.
Post Set (POSTSE)
The POSTSE is responsible for the ownership and management of multiple HRPOST elements.
Handrail Post (HRPOST)
HRPOST element represents the post detail which references the catalogue items or templates as it has a SPREF attribute, the position of the HRPOST is defined with respect to the owning HANDRA in terms of its position along the path and the offset from the path of the HANDRA.
Rail Set (RAILSE)
RAILSE is responsible for the ownership and management of multiple RAIL elements whose physical representation is modelled using a RAIL element.
Handrail Rail (RAIL)
RAIL is used to model the detail representation of the individual RAIL elements and follows the path of the HANDRA, the RAIL references the existing catalogue steel profiles via its SPREF attribute and the position of the RAIL is defined with respect to the owning HANDRA in terms of its position along the path and the offset from the path of the HANDRA.
The RAIL shares the same underlying attributes and behaviour as the KICKPL element.
Handrail Kick Plate Set (HRKPSE)
HRKPSE is responsible for the ownership and management of multiple Kick plate elements whose physical representation is modelled using a KICKPL element.
Kick Plate (KICKPL)
KICKPL is used to model the detail representation of a kick plate and follows the path of the HANDRA, the KICKPL references the existing catalogue steel profiles via its SPREF attribute and the position of the KICKPL is defined with respect to the owning HANDRA in terms of its position along the path and the offset from the path of the HANDRA.
The KICKPL shares the same underlying attributes and behaviour as RAIL element.
Handrail Panel Set (HRPNSE)
HRPNSE is responsible for the ownership and management of multiple HRPANE elements.
Handrail Panel (HRPANE)
HRPANE is the database element responsible for the representation of 'panelised' sections of Handrail where the Panel size is determined by its Panel Size attribute. The detail of the HRPANE is represented using the existing database functionality of TMPL and the route of the HRPANE elements is defined using the RPATH routing object.
Handrail Feature (HRFEAT)
HRFEAT owns HRGATE elements. The HRFEAT also owns RATTA elements which at this hierarchical level provide a connectivity mechanism to/from the boundary of the HANDRA.
Handrail Gate (HRGATE)
HRGATE is an element used to represent access locations along the path of the HANDRA and there can be multiple HRGATE elements in any HANDRA and the position of the HRGATE is managed by the application as a position along the RPATH element. HRGATE elements are managed as negative geometry and penetrate only the HANDRA and additional detail for the HRGATE is represented using the existing database functionality of TMPL.
Terminations (TERM)
The Termination element represents any shape Loops, End Plates, post and so on.
